Engine Identification/Information Help
07 Sep 2016 06:41
Hello all! I have been in a serious on again/off again relationship with my KZ750 LTD Project. At this point, I am trying to pick up a new engine for her. I'll spare everyone the details of why exactly. (However, on that note, if anyone has an 4-cyl 750 engine, or at least bottom end that they are looking to part with, hit me up)
At any rate, I stumbled across the engine pictured below, and it seems like a pretty good buy, but I'm a little curious about some things. The listing says that it came off of an '81 KZ750, but some covers look a little odd, etc. Can anyone shed a little light onto this? Specifically, whether or not there are going to be major discrepancies in the mounting locations?
Thanks!

That looks like a ZR750 engine from around 2000-05 and may require some work to fit it into a KZ750 frame. There have been a couple of topics about it this Summer. A couple of noteworthy features: the ZR has a better oil pump (more flow) & the upper cam chain slipper guide is housed in a bracket bolted to the engine (instead of being fitted into the valve cover).
Fyi: the ZR750 engine nos. begin with KZ750EE

07 Sep 2016 09:35That change was probably from so many damaged guides from not releasing the tension before installing the cover.martin_csr wrote: the upper cam chain slipper guide is housed in a bracket bolted to the engine (instead of being fitted into the valve cover).
Probably would have been cheaper for Kawasaki to just emboss a warning into the valve cover itself.
